| Abstract(in English) | Rayleigh scatter signature of optical fiber measured by coherent optical frequency domain reflectometry (C-OFDR) shows a randomly jagged appearance due to the interference among different scatters. The use of the signature has been proposed for some interesting applications such as fiber identification and temperature (or strain) sensing. However, these applications are limited to short or midrange use and have not been reported for an extended range over the coherence length of a laser used in C-OFDR. In this paper, we demonstrate a method to utilize the scatter signature over the coherence length, and discuss the feasibility of long-range applications. |
